lPATENT CAR-REPLACER.

SPECIFICATION formingvpart of. Letters' Patent No. 540,437, dated J' une 4, 18.95. Application tiled August 20, 1894. Serial No. 520,78@ (N llOdeL) the following to be a full, clear, and exact description ofthe invention, such as will enable othersl skilled in the art to which it appertains to make and use the same, reference be ing had to the accompanying drawings, and

' to the figures of reference marked thereon,

which form a part of this specification.

This invention relates vto improvements in the construction of'car-replacers, and consists of pairs of wreckers frogs adapted to be hooked over, respectively, the right and lefthand rails, and of such construction, as will presently appear, as to positively insure the derailed cars being guided onto the rails with-` out possibility of slipping in action.

Figure 1 of the accompanying drawings represents a portion ot' a railway-track withy one pair of my improved wrecking-frogs or.

car-replaci ng frogs in position, with an axle and a pair of wheels in position to illustrate the operation of the device. Fig. 2 represents a side elevation partly in section.

1 represents the cross-ties; 2, the railroad rails; 3, the axle, and 4 the pair of car-wheels attached thereto.

The two car-replacer frogs, 5 and 6, shown in the drawings, are reversible; that is to say, the frog, 5, which is shown at the right-hand side in the drawings can be reversed in position and placed in connection with the lefthand rail of the track on which trains run in the opposite direction to that lshown in the drawings and, similarly, the frog, 6, can be, for the same purpose, placed in connection with the right-hand rail. This'will be readily understood by those acquainted with this art, or a duplicate pair, reversely positioned may be hooked to the rails if desired. The construction is the saine in each case.

The right-hand frog, 5, consists of an inner block of some suitable hard wood, as oak, 7, having a central longitudinal groove, 8, in its top face, inclined outer end, 9, and on the bottom of its inner side,'a'lon`gitudinal groove, 10, and a longitudinal rib, 1l, along its inner side.

shown to protect the block in use.

'tion between the rail and the frog. grooves in the upper'face ofl the inner wooden block, and in the top sheathing, it will be observed,lare curved at 17 and 18 for the puri pose of guiding the flange ot' the wheel, which .runs in said groove in operation, to the side of'fthe railroad rail and carrying the rim, or 1 1K2 represents metallic sheathing covering the bottomof the inner wooden block, 7, and

the longitudinal side groove in the bottom thereof, said sheathing being upturned at its inner edge onto the side of said block as This sheathing is attached at suitable points to the inner block by any suitable means, as nails, screws, or rivets." V

13 represents the top metallic sheathing of the inner Wooden block. This upper sheathing has a longitudinal groove, 14, correspond ing with the central longitudinal groove in the inner block, a lateral raised ledge, 15, along which the rim of the wheel travels into place, and at its opposite side, a hooked lip, 16, of

- substantially one-half the length of the frog,

said lip, as shown, hooking over the rail and thereby affording steady and secure connec- The tread, of said ywheel onto said rail.

The object of the longitudinal rib, 11, is to afford bearingsupport for 'the edge of the respective sheathings, and of the groove, 10, to provide a space for the flange of the rail and spikes.

The respective sheathings and the inner block are connected together by rivets, spikes, or bolts, `19.

The front ends of the respective sheathings are downturned and preferably welded together, their front edges being serrated, as at, 20, said serrations, or teeth, biting into the adjacent tie as the Wheel of the derailed car ascends the incline of the frog, thereby insuring the steadiness of the frog in use.

As shown in the drawings, the left-hand frog, 6, is of substantially similar construction to that of the frog, 5. It has a similar inner wooden block, 7, inclined front end, 9, and grooved top and bottomk sheathings, 12 and 13. The tlan ge, 2l, however, constituting one wall of the top groove, which serves as a guide for the flange of the rail, does not extend as far, longitudinally, as does that-in the other frog. The top groove in the frog, 6, is also IOO curved, at 22, to guide the iiange of the wheel to the inner edge of the rail.

The operation of my car-replacing frogs will be readily apparent. On a derailed car being drawn to said frogs, the impact of the wheels upon the front ends of the frogs will, by their weight, force down the serrated front ends into bite with the ties on which the frogs rest. Then, as the car is drawn forward, the flange of the, for the time being, right-hand wheel will enter the groove inthe top sheathing while the rim, or tread, of the wheel will ascend the incline and ride up ontothe top of the frog parallel with the hook grip and then, through the medium of the curvatures in said groove, the tread or rim of the wheel will be drawn along the face of the hook railgrip and thence onto the rail. As this operation is taking place, the iange of the, for the time being, left-hand wheel of the car impacts, with the rim, the front end of the for the time being, left-hand frog, forces the teeth or serrations thereof into the tie beneath, and the flange enters the groove and rides up therein while the rim, or tread, of the wheel rides up the raised incline laterally of said groove, the curved flange constituting the inner Wall of the groove guiding the wheel flange to and over the hooked clip and over the rail gripped thereby, said guiding of' the flange and rail rim of the wheel onto the rail, in this instance, being facilitated by the curvature, 23, of the iiange, 24, on the sidewise extension, 25, of which the rim of the wheel travels.

Supposingthe drawings to represent the application of lny replacer-frogs to the up-track of a railroad, by simply transposin g said frogs they are equally well adapted for use on the `down track, as will be readily apparent.

It will be seen that by forming my frogs with extended grooves to receive and guide the respective flanges of the wheels, with broad side bearings for the rims, or treads, of the wheels, and forming the grooves and their side walls with curves, as explained, the wheels will be readily raised and guided onto the tracks without the posibility of their slipping at any portion of their transit as the wheels are held in position from the time they strike the inclines until they are guided onto the rails.

In practice two pairs of frogs are hooked over the rails; one pair reversely positioned to those shown at 5, 6, and located a short distance away.

I am aware of the patents heretofore respectively granted to Schreiner on the 22d day of December, 1868, numbered 85,137; Fosdck on the 30th day of October, 1883, nu mbered 287,528; Toombs on the 30th day of October, 1883, numbered 287,738; Fisher on the 4th day of April, 1893, numbered 494,806; Green on the 25th day of April, 1898, numbered 496,055; Mooney on the 31st day of October, 1893, numbered 507,829; and Reaney on the 30th day of January, 189i, numbered 513,531; and disclaim each of said patents severally as anticipatory of my invention herein shown and described.

Having thus described my invention, what I claim is In car replacers the central block tapering to a point having an edge adjacent to the rail, and provided with a bottom sheathing 13 following the conformation of said block and having aiiixed to its upper surface similar sheathing following the contour of the upper surface of said block and bent upon itself three times to form respectively the groove 14 adapted to receive the flange of the wheel 4 and the hooked rail grip 16, whereby the device is held fixedly to the rail, the said upper sheathing terminating forwardly in a curved, pointed, serrated end 20 to grasp firmly the tie of the roadbed; the whole correlated and combined as herein shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
